Sometimes, you end up outside when you didn't plan on it. You are running errands and the kids are restless and you hit a park or you go to an activity and part of it ends up being outside, or you are planning to be outside for just a little bit and it ends up being a lot longer, etc.
I don't like being caught out in the sun for longer than expected without protection for my kids and I (and husband too), so I bought this cute travel container (see the blue/white striped bottle) at Target and I put sunscreen in it. I tossed it, along with sunblock lip balm (Sun Bum is my fav), into a ziplock sandwich bag and keep it in my purse all summer long.
Now I won't get caught un-prepared for the sun, and none of us will get an accidental sun burn. Although I don't think we've ever gotten one on purpose either - LOL!
My favorite sunscreen of all is DeVita. I use the DeVita Solar Body Moisturizer for our bodies and kids' faces, and I use the Solar Protective Moisturizer for my face in the mornings- because it blends amazing under makeup.
These DeVita sunscreens received a #1 ranking (which is the highest) on the EWG (Environmental Working Group) website, where they test and review safety for sunscreens. I always check the EWG's sunscreen guide before I buy any sunscreen.
